(f)
Release SYSTEM TEST switch. Ensure all brakes release momentarily and then apply.
(g)
Release parking brake and connect electrical connector D928 to shutoff valve. Ensure inboard and outboard ANTISKID INOP lights go off.
(16)
Test Right Inboard Antiskid Control Valve
(a)
Disconnect electrical connector D930 from right inboard antiskid control valve. Ensure inboard ANTISKID INOP light on pilot's panel and RI light on antiskid control shield come on.
(b)
Place COMPONENT TEST switch on antiskid control shield to VALVE position. Ensure inboard ANTISKID INOP light and RI light go off. Release COMPONENT TEST switch. Ensure inboard ANTISKID INOP light and RI light come on.
(c)
Connect electrical connector D930 to valve. Ensure inboard ANTISKID INOP light and RI light go off.
(d)
Ensure parking brake is release d and disconnect electrical connector D928 from shutoff valve. Ensure inboard and outboard ANTISKID INOP lights come on.
(e)
Set parking brake and place SYSTEM TEST switch on antiskid control shield to LEFT position. Ensure right inboard and right outboard brakes release and left inboard and left outboard brakes remain applied.
(f)
Release SYSTEM TEST switch. Ensure all brakes release momentarily and then apply.
(g)
Release parking brake and connect electrical connector D928 to shutoff valve. Ensure inboard and outboard ANTISKID INOP lights go off.
(17)
Test Right Outboard Antiskid Control Valve
(a)
Disconnect electrical connector D932 from right outboard antiskid control valve. Check that outboard ANTISKID INOP light on pilot's panel and RO light on antiskid control shield come on.
(b)
Place COMPONENT TEST switch on antiskid control shield to VALVE position. Check that outboard ANTISKID INOP light and RO light go off. Release COMPONENT TEST switch. Check that outboard ANTISKID INOP light and RO light come on.
(c)
Connect electrical connector D932 to valve. Check that outboard ANTISKID INOP light and RO light go off.
(d)
Check that parking brake is released and disconnect electrical connector D928 from shutoff valve. Check that inboard and outboard ANTISKID INOP lights come on.
(e)
Set parking brake and place SYSTEM TEST switch on antiskid control shield to LEFT position. Check that right inboard and right outboard brakes release and left inboard and left outboard brakes remain applied.
(f)
Release SYSTEM TEST switch. Check that all brakes release momentarily and then apply.
(g)
Release parking brake and connect electrical connector D928 to shutoff valve. Check that inboard and outboard ANTISKID INOP lights go off.

ANTISKID VALVE - INSPECTION/CHECK
1. Antiskid Valve Check
A. General
(1) The purpose of this check is to determine if the individual antiskid valve has excessive internal leakage by observing pressure decay as registered on the brake pressure gages in the control cabin.
B. Equipment and Materials
(1) Gear Ground Lock Assembly (Ref 32-00-01)
C. Check Antiskid Valves
(1)
Ensure gear ground lock assembly is installed in nose gear (Ref 32-00-01).
(2)
Depressurize hydraulic systems A and B (Ref 29-11-0, and 29-12-0).
(3)
Turn flight control and spoilers off (Ref Chapter 27).
(4)
Depressurize brake hydraulic system to brake accumulator precharge pressure (approximately 1000 psi) by operating brakes fully 8 times.
(5)
Record pressure registered on brake pressure gages.
(6)
Turn one hydraulic system B pump on (Ref 29-12-0)
(7)
Open ground interconnect valve.
(8)
Set parking brake.
